SIDE FRAME.

Application led September 28, 1923. SerialNo. 665,446. i i

My Ainvention relates,Y to side frames for car trucks and moreparticularly to a. wrought metal construction of side frame which isvery strong and stiff but comparatively light in weight and in whichmaintenance charges are reduced to a minimum.

One'of the principal features ofthe inventionuesides in the productionof a side frame composed of a plurality of separately l0 formed wroughtmetal sections each having an inner and an outer side wall portion, saidY sections being adapted to be abutted in horizontal planeslongitudinally of the side frame .and united to provide a constructionof great strength value, said construction forming in effect continuousinne-r and'outer side Walls each having a plurality of top arch barportions, bottom arch bar portions, and truck Acolumn ortions.

Another object o the invention resides in the provision of a built-upside frame in-V volving a compression member, a tension member and truckcolumn members all of which are formed from relatively small sheet-metalblanks capable of being easily ianged, folded and united, said membersbeing referably abutte relation.

Another object of the invention is to providepa Wrought metal side framehaving a tension member, a compression member, and

two intermediate truck column members, the

said members being connected by Welding or riveting yto .provide-'averyv strong and du.

' iable side frame -whichcan be economically manufactured due to thelarve saving of material resulting .from the. tformation of each of saidmembers from -a separate blank of l sheet-metal. i

A still further object of the invention is to provide a wrought metalside frame composed -of separately formed compreion member, tensionmember and truck columns, the compression and tension members beingfirmly united at their end portions by means involving abent extensioncarried.- by one of said" members and adapted to bridge the other, saidbent extension beingfirmly con nected to both of said members uponv eachside of their junction..

The invention furtherresides in the method of manufacturing car truckside\frames which consists in producing a plurality of separately formedside frame members such as the compression member, tension member,

hereinafter appear.

connected 'in' superimposed and truck .column members, each `ot' saidmembers being produced from .a sheet-metal `blank shaped to providecorresponding side frame .portions lying upon opposite sides of anv axisof symmetry dividin the blank, flanging the marginal edges o each blank,folding said blanks, and uniting the folded blanks with their adjacentedge portions disposed in planes extending transversely of the verticalloads received by the side frame members.

\ There are other features bf the invention A.

pertaining to the particular relation of the parts and details ofconstruction as"'wi1l In the drawings illustrating the invention, thescope whereof is pointed out in the claims: p Figure 1 is a View insideelevation of a wrought metal`car truck side frame constructed inaccordance with my'invention.

Figure 7 is a top plan View struction shown in Figure 6. l l

Referringy to the drawings in which sim ilar reference charactersdesignate corresponding parts inthe several views, my improved sideframe is composed of.a compression member 1, a tension member 2. and

bolster 0r truck column members 3, said 7 truck column',m`embers beingadapted to unite the compression and tension members intermediate theirends to form the bolster "opening 4. The side frame members are eachformed from a sheet-metalblank having corresponding side frame portionsdiside of an axis of sym united by an of the coning thektopv' arch` barport-ions which are preferably shaped to have the eiect of a camberedcompression member. Stienmg flanges 7 are provided on the lower edgespof the top arch bar portions, said iianges being inturned and adaptedto. rein-force the spaced side walls `o'f the compression 111cm-,

ber. The lower edges vot the inner and outer side walls of thecompression member` between the truck 'columns are also provided withinturned stilening ianges 8, said flanges bordering ,the upper portionof the outer sheet-metal wall 12, said Walls convso " bolster opening.rI `he respective end poi'- tions ofthe side walls of the compressionmember, and more especially the lower 'ledges 9 thereof, areadapted tobe united with correspondingly vormed upper edofe portions 10 at therespective ends of the tension member 2.

The tension member 2 is formed from a sheet-metal blank havingcorresponding side frame portions disposed upon f each side of an aXisof symmetry dividing the blank. The tension member is provided with aninner sheet-'metal wall 11 and an v' are adapted to be connected toadjacent -of an axis of symmetry edge portions 17 of the truck columns3.

The truck column members are each formed from a sheet-metal blank havingin o ner and outer side wall portions 18 and 19,

respectively, .disposed uon opposite sides Stiti'ening ianges 2O extendinwardly from the outermost edge portions of the truck columns, saidstiffening flanges providing ,y contmuations of the tiffening'ilanges 7of `the compression mem er and the stiiening flanges 13 of the tensionmember. The inner opposed faces of the truckv columns are adapted toreceive bolster wear plates, said inner faces at'their lower ends beingoffset, as at 21, and continued downwardly to overlie invertical-alinement the inwardly leX- tending stiflening ianges 14provided on the upstandingportions of the tension member and borderingthe bolster opening. The upper endsof the truckvcolumn members, and moreespecially the edge portions 22 thereof, are adapted to be united withad jacent edge portions 23 depending from the compression member 1. Theinner opposed l faces of the truck column members provide continuationsof the` ividing the blank.'

inwardly extendingy stil'enmg Hanges 8, the'end portions of said .'angesbeing bent around the -upper corners of the bolster ooeningand disposedto I overlie said inner opposed faces.

The means uniting the ltruck columJns at their respective ends to thecompression and tension members involves a plurality of welds 24, saidwelds being designed to unite therespective abutting edge,4 portionswith the inner and outer side Walls of the compression member disposedin vertical aline- *ment with the respective' inner and outer member,.said respective side wall portions being united to produce in eiectcontinuous integralshee't-metal side walls of maximum strength value. ytransversely to the direction ofthe vertical loads received by the sideframe. While,y I havev disclosed welding means to efgfect the union ofthe truck columns with the compression and tension' members, it will beunderstood that rivets andv othei` connecti-- ing means may also beutilized, it being desirable. however, to maintain the side walls of thecompression member in .overlying relation to the side walls of thetension member whereby the vertical load will be transmitted :toportions best adapted to withstand thestrains. l

The compression and tension members are united at their ends b means ofa relatively long Weld 25 prefera ly extending'the full The welds 24 aredisposed.

side walls of the truckcolunns and tension length of the abutting edges'9 and 10 of the v respective members. The'side wall portions of thecompression member at its ends are adapted to overlie the side wallvportions at the ends of the tension member, the union of said side wallportions at these points providing in effect an integral continuation ofthe respective inner andvouter side walls of the side frame whereby boththe vertical and loo lo gitudinal loads are effectively received by s'thescompression and tension members.

In Fi ure 6 a modified construction is shown w erein the end portions ofthe comressionand tension membersv are also united y a bendableextension 26 provided on the compression.. member, -said bendableeXtension having flanges 27 disposed against the inner opposed faces ofthe side wall portions of the compression and tension members, saidflanges being connected to the respective sidel walls by means of rivets28. The flanged portions of the bendable extension are -designed tobridgey the weld joint between the compression and tension members 4andprovide a very rigid construction at the end of the side frame. In thisconstruction theJ length of the compression member is slightly reducedto permit of the bendable extension being formed from the same blankwithout adding materially to the amount of metal used. f My improvedmethod of manufacturing wrought metal car truck side frame consists informing'each of the side frame members,

sch as the compression and tension members and. truck columns. from asheet-metal blank havingcorresponding side frame portions which aresymmetrically disposed with respect to an axis of symmetry of -the blankpassingbetween them, then bending corres onding portions of the blanktov form anges, then bending each blank along aline parallel to its axisof symmetry, and/'inally uniting the respective blanks with theiradjacent edge portions disposed transversely to the direction of thevertical loads of the Y side frame, the adjacent side frame portions ofthe respective sideframe members producing 1n effect continuous mnerandouter side Walls havindglsilnwardly extending stiiening anges relation.I

It will be perceived that a truck side frame embodying my invention canbe economically manufactured from relatively small blanks which arecapable of being easily-assembled and iirmly` united. It will be notedthat a osed` 1n uninterrupted car truck side frame constructed inaccord,
